Researchers' app extends battery life when you're multitasking
Battery life on a phone is bad enough most of the time, but it can be particularly rough if you're fond of split-screen multitasking. Researchers might have a way to wring a little more power out of your device, however. They've developed an app, MultiDroid, that promises to extend battery life on Android phones with OLED screens. The software dynamically lowers the brightness in non-critical parts of the screen depending on how you switch between apps and how long you've left a section idle. Fire up a YouTube video on one half of your screen, for example, and the browser you've left idle in the other half will grow darker.
